authenticity verification of modules and core with SHA512 cheksums and developers' signatures?

Thank you for sharing your idea for improving Drupal.

We are working to decide if this proposal meets the Criteria for evaluating proposed changes. There hasn't been any discussion here for over 8 years which suggests that this has either been implemented or there is no community support. Your thoughts on this will allow a decision to be made.

Since we need more information to move forward with this issue, the status is now Postponed (maintainer needs more info). If we don't receive additional information to help with the issue, it may be closed after three months.

Thanks!

I think this should be closed as outdated, Automatic Updates → uses PHP-TUF to improve supply chain security, see https://rugged.works/background/tuf_for_humans/ for more information.
